JThose are on the cheaper and slower side of consumer SSDs. They will not perform well with sustained load and the primarily sync writes that Ceph does. The recommendation for enterprise SSDs with power loss protection (PLP) is there for good...

Jjdancer replied to the thread [SOLVED] Trying to enable nested virtualization results in perfomance loss on vm.I don't run nested virtualization using Windows guests but do with Linux guests especially with Proxmox, ie, phystical Proxmox -> vitual Proxmox -> Linux guest. I do use CPU type of 'host' as your screenshot shows. As for number of cores, I see...

Jjdancer replied to the thread [SOLVED] Dell R730 cannot boot Proxmox 9 kernel (boot loop after install).For 13th-gen Dells, enabling X2APIC & IOAT DMA resolves the issue. I don't use SRV-IO.

Jjdancer replied to the thread VMware Migration - Scenario & Seeking Advice.I run Proxmox on 10th through 14th-generation Dells at work. Yup, this is with latest Proxmox 9.1.x with latest 7.0.x kernel. No issues. I just made sure the machines has the latest firmware and BIOS/UEFI. I do NOT use any RAID controllers...

Jjdancer replied to the thread [SOLVED] Support for PERC H310 Mini on PVE9.You are better off flashing the 12th-gen PERCs to IT-mode via https://fohdeesha.com/docs/perc.html Do NOT skip any steps and record the SAS address. No issues in production.

Jjdancer replied to the thread 9.1.1 Installation issue with PERC H730 Mini.Dell HBA330 mini-mono versions are definately for 13th- and 14th-gen Dells. For 12th-gen Dell PERCs (H310/H710/H710P/H810), use https://fohdeesha.com/docs/perc.html. No issues in production. Do NOT skip any steps and take your time. If you want...

Jjdancer replied to the thread Ceph 20.2 Tentacle Release Available as test preview and Ceph 18.2 Reef soon to be fully EOL.Been testing EC pools with plugin=ISA technique=reed_sol_van with VMs with additional storage optimizations. Weirdly enought, it's faster in read operations than replication. Not complaining.

Jjdancer replied to the thread Enterprise grade SSD recommendation for Proxmox host.This. Look for PLP. I will also look for high endurance. I use Intel DC-S3710s for their 10 DWPD endurance.

Jjdancer replied to the thread Cluster setup and HA configuration suggestions.I've been migrating from VMware vSphere to Proxmox Ceph at work on 13th-gen Dells. Ceph really, really, really wants homogeneous hardware, ie, same CPU, RAM, NIC, storage, storage controller, firmware, etc, etc. I swapped out PERCs for Dell...
-
Jjdancer replied to the thread How to Configure iSCSI shared storage for thin Snapshots properly.Seeing that the MD3200i is a legacy SAN, maybe cheaper to migrate to Ceph. Been migrating VMware legacy SAN infrastructure to Proxmox Ceph. IMO, need a minimum of 5-nodes. So, can lose 2 nodes and still have quorum. Isolated switches for Corosync...

Jjdancer replied to the thread 9.1.1 Installation issue with PERC H730 Mini.A better option, IMO, is to use a pure IT-mode storage controller like a Dell HBA330. Extremely cheap to get. Uses the much simpler mtp3sas driver and don't have to deal with PERC storage drama. No issues in production.

Jjdancer replied to the thread Repurposing vxrails hardware with Ceph.Been migrating 13th-gen Dells (R630s & R730s) from VMware to Proxmox Ceph. Clusters range from 3- to 9-nodes, all odd number for quorum. All hardware is the same (RAM, CPU, NIC, storage, storage controller, firmware). Swapped out PERCs for Dell...

Jjdancer replied to the thread Cluster best practices.Considered best practice that cluster traffic have it's own network/vlan. I just create a additional vmbr (ie, vmbr1 or whatever number you want [best to use a VLAN number, if used]) and when I create the cluster, make sure it uses that network...

Jjdancer replied to the thread Establishing Proxmox VE as a Cross-Platform Hypervisor with Full RHEL/EL9 Ecosystem Support.Most large organizations treat Proxmox VE in terms of accrediation/ATO as an appliance. Since PVE is a hypervisor platform. It's NOT meant to directly run workloads. Workloads are done via VMs/LXCs. Same with PBS & PDM. It's treated as an...
-
Jjdancer replied to the thread Optimizing PERC Storage Configuration for Proxmox on the R640.A better option is to avoid the PERC HBA-mode drama and get a Dell HBA330. It's a true IT-mode storage controller based on the LSI3008 chip. Real cheap to get. Just make sure to remove any existing virtual disks prior to use and flash to latest...

Jjdancer replied to the thread Creating a set of Proxmox Servers for a class.Currently using a full-mesh 3-node Proxmox Ceph cluster using Resource Pools. Created individual accounts and have them log in using the Proxmox VE authentication realm. Each VE account has PVEAdmin permissions to the Ceph pools and Networking...

Jjdancer replied to the thread High latency on proxmox ceph cluster.Use consumer SSDs at your peril. They fail and fail spectacularly. Only real solution is enterprise SSDs with PLP (power-loss protection) and for endurance.
-
Jjdancer replied to the thread best practices network for the PVE Cluster.This. Since I follow the KISS principle, I use active/passive setup. I believe even VMware recommends this before I migrated to Proxmox.

Jjdancer replied to the thread Proxmox 6 mpt3sas Debian Bug ICO Report 926202 with Loaded Controller.Don't know if matters but latest firmware for Dell HBA330 is 16.17.01.00 A08. May or may not help your issue. No issues on 16-drive bay R730s in production.
